    The Eclipse custom ROM is very popular among Android users as it has a dark user interface, fun features and apps that can help you increase the performance of your smartphone (you’ll have access to the internal system of your Motorola Droid RAZR M and you’ll be able to improve the battery life, add a new user interface, gain more speed as well as other tricks)and since this custom ROM is based on the Android 4.2.1 Jelly Bean, you’ll be able to enjoy all the feature the JB OS brings.


    Before you start to update your smartphone, make sure the following requirements are met:

    1. Back-up your Motorola Droid RAZR M. Since this update is a custom ROM and not an official over the air update, you’ll have to take some risks and for that reason it’s better to be safe than sorry and back-up everything before you start. Use our back-up tutorial or any other method you prefer.
    2. Your Droid RAZR M needs to be rooted in order to install a custom ROM, so make sure you root your device first.
    3. You also need to install a customer recovery image, such as CWM recovery.
    4. Your computer needs to have internet access.
    5. An USB cable and microSD card is also necessary.
    6. Your antivirus, firewall or any other security programs you use need to be disabled or better yet, uninstalled as it will try to block the update.
    7. USB debugging needs to be enabled on your smartphone.
    8. The battery needs to be at least 60% charged, but you can charge it to 100% just to be on the safe side.
    9. This tutorial is especially designed for the Motorola Droid RAZR HD, using it on a different model or device, may and most likely will brick it.
    10. Also, by applying this update and rooting your device, the warranty will be voided. You will be able to restore your warranty though, just by updating your smartphone with an official update or by downgrading it to the stock ROM.
    11. Lastly, we are not to be held responsible for anything that may happen to your device for following this tutorial, so proceed only if you’re absolutely certain about this.

    Updating Your Motorola Droid RAZR M to the Jelly Bean 4.2.1 OS

    1. Download the update file on your computer.
    2. Connect your Droid RAZR M to your computer using the USB.
    3. Copy-paste the files you’ve downloaded to your smartphoe’s microSD card.
    4. You can now remove the USB cable as we won’t be working with the computer anymore.
    5. Reboot your smartphone into recovery mode and select Wipe Data Factory Reset -> Wipe Cache Partition and Wipe Dalvik Cache.
    6. Then go back to the Main Menu and select Install Zip from SD Card -> Choose Zip from SD card.
    7. Select the file you’ve downloaded and then start the flashing operation.
    8. After the installation process is finished, select +++go back+++.
    9. Then select Reboot System Now.
    10. And this is pretty much it! Your Motorola Droid RAZR M has been updated to the Android 4.2.1 Jelly Bean.

    Note: If you’re having issues with booting your device, you need to repeat the wipe, so just start the process from step 5.
    Note II: It will take a few minutes for your smartphone to boot the first time, so be patient and wait until it restarts into the new operating system.

    Would you define what rooting a device means? I am comfortable with cellphones, but am not much of a high tech experimenter, and thus don't understand the term "rooting", since I assume it involves going beyond the general setup of the device.

    Rooting is getting 'admin' access to your phones software. It makes it so you can do whatever you want with it, like loading a custom ROM.
